laravel无法准备要序列化的路线.使用闭包 [英] laravel Unable to prepare route ... for serialization. Uses Closure

问题描述

当我清除Laravel 5.2项目中的缓存时，会看到以下错误消息:

[LogicException] 无法准备要进行序列化的路线[面板].使用闭包.

我认为这与路线有关

Route::get('/article/{slug}', 'Front@slug');

与控制器中的特定方法相关联:

public function slug($slug) {
    $article = Article::where('slug',$slug)->first();

    $id = $article ->id_article ;

    if ( ($article=== null) || (is_null($id)) ) return view('errors/Db');

    else return view('detail')->with(array('article'=> $article,  'title'=>'My title - '.$article->title)); 
}`

简而言之，从主视图中，我传递了$ slug，这是文章的短链接，其中$ slug在数据库中是唯一的，我确定了记录，然后将其内容传递给了详细视图. /p>

当我编写该方法时，我没有任何问题，但实际上它就像一个魅力一样工作，但是在清除缓存后，我得到了该错误，并且主视图中的链接没有显示任何短代码.

我在哪里做错了?

解决方案

我认为这与路线有关

Route::get('/article/{slug}', 'Front@slug');

与控制器中的特定方法相关联:

不，那不是.错误消息来自route:cache命令，不确定为什么清除高速缓存会自动调用此错误.

问题是使用闭包而不是控制器的路由，它看起来像这样:

//                       Thats the Closure
//                             v 
Route::get('/some/route', function() {
    return 'Hello World';
});

由于闭包无法序列化，因此当您有使用闭包的路由时，就无法缓存路由.

When I clear caches in my Laravel 5.2 project, I see this error message:

[LogicException] Unable to prepare route [panel] for serialization. Uses Closure.

I think that it's related with a route

Route::get('/article/{slug}', 'Front@slug');

associated with a particular method in my controller:

public function slug($slug) {
    $article = Article::where('slug',$slug)->first();

    $id = $article ->id_article ;

    if ( ($article=== null) || (is_null($id)) ) return view('errors/Db');

    else return view('detail')->with(array('article'=> $article,  'title'=>'My title - '.$article->title)); 
}`

In short, from a master view I pass $slug, that is a shortlink to the article, with $slug , which is unique in the database, I identify the record and then I pass it's contents to the detail view.

I didn't have any problem when I wrote the method, infact it worked like a charm, but after I cleaned caches, I get that error and the links in the master view don't show any shortcode.

Where am I doing wrong?

解决方案

I think that it's related with a route

Route::get('/article/{slug}', 'Front@slug');

associated with a particular method in my controller:

No, thats not it. The error message is coming from the route:cache command, not sure why clearing the cache calls this automatically.

The problem is a route which uses a Closure instead of a controller, which looks something like this:

//                       Thats the Closure
//                             v 
Route::get('/some/route', function() {
    return 'Hello World';
});

Since Closures can not be serialized, you can not cache your routes when you have routes which use closures.
